Hamilton reaches 400 grands prix in São Paulo

Lewis Hamilton became only the second driver in Formula 1 history to reach 400 grands prix, after Fernando Alonso, at the São Paulo Grand Prix. Hamilton started from 20th and climbed into the top 10 on a lively opening lap, though he had to give up a place to Ollie Bearman after an off-track pass.

Hamilton and Charles Leclerc were both caught out in the middle of the field. Hamilton's early switch to slicks brought little benefit, and his decision to stay out when rain returned saw him finish ninth, his worst result of the year and one place behind Leclerc. Ferrari's collective result was its poorest of the campaign.

Cadillac suffered a setback before the start when Valtteri Bottas's car developed a cross-threaded wheel nut on the grid. Mechanics could not repair it, and Bottas did not start, the first Did Not Start for Cadillac in Formula 1. Team Principal Marcin Budkowski said the team would investigate the issue to prevent a repeat.
